Comms problems in Arma 3 (ACRE2 + TFAR)

I have been playing Arma for a moment now and a problem has come up when playing (mostly when in action and during contacts, not really during briefing and debriefing) on private modded servers with units for their operation using TS3 as a radio and direct speak channel (tried with both ACRE2 and TFAR)
What happens with ACRE2 is I either only hear TS3 with no in-game sound or I mainly hear the in-game sound, barely the radio and direct talk pretty much not at all.
What happens with TFAR is a bit different. I still hear either one or another more but not as badly with ACRE2, rather others can’t hear me at all apparently.

Has anybody had this problem before or knows how to fix this?
